If you are unable to activate your license key or get validation error alerts, verify the following solutions:
- White Space Issue:
Make sure you didn't accidentally copy any trailing white spaces before or after the license key. - Outbound Connection Blocked:
Sometimes your web hosting server blocks outbound connections (cURL requests). Contact your hosting support to verify that your server is allowed to make API requests to the license server at licensecart.com. - Max Activations Reached:
Check your License Cart profile to ensure you have not exceeded the site limit for your active license plan. If you have, you will need to deactivate the key from one of your other sites first.
